2.MAC /SN 码烧录​

 /sys/block/mmcblk0boot1/force_ro

echo "30A61219892D" > mac0.txt

xxd -p -u -r mac0.txt > mac0.bin

dd if=mac0.bin of=/dev/mmcblk0boot1 count=6 bs=1 seek=64

echo "30A61219892E" > mac1.txt

xxd -p -u -r mac1.txt > mac1.bin

dd if=mac1.bin of=/dev/mmcblk0boot1 count=6 bs=1 seek=80

SN：

echo "HQATEVBAIAIAI0001" > sn.txt

dd if=sn.txt of=/dev/mmcblk0boot1 count=17 bs=1

echo "HQATEVBAIAIAI0002" > sn.txt

dd if=sn.txt of=/dev/mmcblk0boot1 count=17 bs=1 seek=32]]>
